摘要:
A switching combiner unit (SCU) that combines coherent RF or microwave outputs from multiple power amplifier units (PAUs), each of which can be switched between an on-line mode (on-line PAU), during which the PAU amplifies a coherent instance of the same RF or microwave input signal and delivers that amplified input signal to an output, and a standby or off-line mode (standby/off-line PAU), during which the PAU does not amplify an instance of the same RF or microwave input signal or deliver an amplified input signal to the output, comprising: an input port that connects to each of the PAU outputs; a control signal input that receives one or more control signals that indicate whether each PAU is in the on-line or standby/off-line mode; signal combining circuitry that coherently sums the outputs from all of the on-line PAUs, while simultaneously isolating the standby/off-line PAUs from the output of the SCU and the outputs of the on-line PAUs; and an SCU output port that delivers the coherently summed outputs from all of the on-line PAUs.

A cableless high power RF or microwave amplifier that amplifies an RF or microwave signal comprising: an input signal divider (DIV) that has a DIV input connector that receives the RF or microwave signal and that divides this input signal into multiple sub-input signals, each of which is delivered to a DIV output connector; multiple power amplifier units (PAUs), each of which has a PAU input connector that receives an RF or microwave signal and a PAU output connector that delivers an amplified version of the received RF or microwave signal; and an output signal switching combiner unit (SCU) that has multiple SCU input connectors and that coherently sums the signals at the multiple SCU input connectors and delivers this to an SCU output connector, wherein each of the PAU output connectors are electrically connected to a different one of the SCU input connectors without connecting cables.

摘要:
A scalable radio frequency (RF) generator system including at least one power supply, at least one power amplifier receiving input from the power supply, and a power supply control module, and a system controller. Output from the at least one power supply can be combined and applied to each of the power amplifiers. Output form each of the at least one power amplifiers can be combined to generate a single RF signal. A compensator module controls operation of the at least one power supply. The compensator module, system control module, and power supply controller communicate in a daisy chain configuration.

A communications amplifier system comprises a primary amplifier circuit (13), a backup amplifier circuit (14) and a bypass circuit mutually exclusively selectable through a relay switching means (12) which is automatically activated to bypass the primary amplifier circuit (13) with the backup amplifier circuit (14) or the backup amplifier circuit (14) with the bypass circuit in the event of malfunction. In the standby mode, the backup amplifier is not connected to DC power or RF signal input.

Disclosed is a radio frequency unit, including a power amplification module (9), a filtering module and a signal connector (1); where one end (A) of the signal connector is connected to the filtering module, and the other end (B) is connected to the power amplification module; the power amplification module is provided with a power amplification connector (2); a guide structure for guiding the power amplification connector to be coaxially aligned with the signal connector is formed on one end of the signal connector connected with the power amplification module; and through the guide structure, the power amplification connector is coaxially connected with the signal connector. Through the above technical solution, the utility model solves the problem that an existing radio frequency unit cannot satisfy an assembly requirement due to small axial tolerance and radial tolerance in an assembly process. The connection between the power amplification module and the filtering module through the signal connector is facilitated by means of the guide structure used for guiding the power amplification connector and the signal connector to be coaxially aligned. Compared with an existing signal connector, the utility model has the advantages of low cost, space saving, flexible installation mode and simple technology.
